Project Cornerstone's mission is to educate the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone) through hands-on learning in Science, Technology, Engineering and Mathematics (STEM). Construction aggregates are used to build roads, houses, schools and all other infrastructure; they are the cornerstone of our communities.

Superior Ready Mix was spotted yesterday in a community off of Monroe Street near Kensington. In preparation for repaving the street for this neighborhood, they were removing the existing pothole filled pavement into trucks. This original material will then be recycled and reused to provide new pavement for this community.
